Polimorfismo de los genes k-caseina, β-lactoglobulina y α-lactoalbumina en razas bovinas criollas colombianas.
(2009-12-07)
Se tomaron 354 muestras de sangre de ocho razas bovinas criollas (30 individuos por raza): Blanco Orejinegro (BON), Caqueteño (CQT), Casanareño (CAS), Costeño con Cuernos (CCC), Chino Santandereano (ChS), Hartón del Valle ...
Influence of subsurface oxidation on the structure, stability, and reactivity of grafted Si(111) surfaces
(American Chemical Society, 2008-09)
We investigated the influence of intermolecular interactions and subsurface oxidation on the structure, surface bonding, and reactivity of compact monolayers of small organic and inorganic molecules bound to the Si(111) ...

Synthesis, structure, and reactivity of nitrosyl pincer-type rhodium complexes
(American Chemical Society, 2009-03)
Pincer-type linear nitrosyl Rh(I) complexes, Rh(PCPBu)(NO)][BF4] (2) and [Rh(PCPBuCH2)(NO)][BF,4] (8), are reported (PCPBu = 1,3-bis[(di-fer/-butylphosphino)methyl]-2,4,6-trimethylbenzene). Complex 2 was synthesized by ...
A family of ruthenium complexes containing the non-innocent ligand o-benzoquinonediimine. An infrared structural interpretation
(2003)
It has been shown that innocent ligands always contribute with a similar electron density to a metal centre in a complex regardless of which other innocent ligands are bonded to the same centre, while non-innocent ligands ...
Cosmic ray–ice interaction studied by radiolysis of 15 K methane ice with MeV O, Fe and Zn ions
(2013)
Methane (CH4) ice is found in the interstellar medium and in several bodies of the Solar system, where it is commonly exposed to cosmic rays and stellar winds. The chemical, physical and structural effects induced by fast ...
Nucleophilic addition reactions of the nitroprusside ion - The case of O-methylhydroxylamine
(Wiley VCH Verlag, 2012-10)
The kinetics of the reaction between aqueous solutions of [Fe(CN) 5NO] 2- and NH 2OCH 3 has been studied by means of UV/Vis spectroscopy and complementary solution techniques, FTIR/ATR spectroscopy, mass spectrometry, and ...
